Y To all whom t may concern.'

Be it known that I, MARIE B. DUFFY, a, v citizen pf the United States, and a 4resident of Toledo, in the county of Lucas and State of Ohio, have made an invention appertaining to a Window Guard; and do hereby declare the following to be a full, clear, and exactY description of the invention, such as will enable Vothers skilled in the art to which it appertains't'o make and use the same, reference being had to the ac-v companying drawings, and to the` characters of reference marked thereon, which form a part of this specification.

My invention has for its object to provide an eiicient, Vsubstantially burglarfproof guard for an open window. The invention provides a means for locking a window in an open position, and also a grating thatY cannot be readily opened from without,

which effectually closes thespace left open by the window sash. It is so. constructed that it cannot be readily jimmied and so that'it may be readily applied and opened and closed. It also provides fmeanswhereby it may be either folded into the window frame or swungv to 'one side on the window casing. u j l Y AThe invention may be contained in structures which intheir details may bevaried. TQ illustrate a practical application of the inventionfI have selected a window guard, containingmy invention as an example ofv structures containingV the invention and shall describe it hereinafter. The structure selectedis illustrated in the accompanying in Fig. 6.

known. Y The 3 ,the forintof the inj' 1 vention illustrated in Figs. 1, 2 andrcomprises a Vpair of lazy tongs, eformedof metal strips of suitable width and thickness to efectuallyprotect the opening produced when the sash 2k is raised a shortdistance in the frame 1. The lazy.v tongs are provided with suitable members :torl interconnecting them and also torconnectingthem to the window frame. V'llhey` are provided with the l comparatively Widestrips 51 to which, the

inner ends of the lazytongs are connected, one or more of the adjoining strips of each of the lazy tongs being pivoted toa strip 5 and one or more of the adjoining stripsbeing connected to a strip 5 by means of a pin and slot connection 6. VAlsoeach of the lazy tongs is connected to a-strip`7, one or more of the adjoining strips of the lazy tongs being pivoted to the strip 7,` and -one or more ofthe adjoining stripsbeing connected to the strip by a pin and slotconnection 8. The strips 7 are. hingedly connected to the strips 9 and the strps9 are securedfto the window frame. Thus'the strips 5 and the lazy tongsV 4 may lbe pushed back to the pivot-s 10 toene frame and` swung onthe side of thewindow frame.

In order. to secure the guard to the Sill a U bracketll is secured tothe window sill.-

The U bracket 11 is provided with slots'12v that extendfromthe edges of the bent portion of lthe U bracket, leaving between the 1 ends of the slots a tongue 13 that is integral with the sides ofthe bracket. The strips 5 are provided with slots 14 :that fit the .Y f* tongue 13. When therstrips 5 are placed contiguous the slots 14 are fitted to the tongue 13 and the lower ends of the strips 5 fit .in the slots 12. This'preven'ts the guard from being raised andalso from being pushed inward or pulled outward, and thusthe lower ends of thev strips are held in position. The upperend of the strips 5, andl consequently the upper edge off the central-.,-A portion. of the -guard-Lis.held in'a similar f manner, asby'the strips 15 that are` secured tothe stripsyand the bracket 16.; The strips 15 are bent angularly inward `so ,as

to place the upper edge of the guard substantially within-the planeetthe window sash 2 and yet affordKL a connection betweenr the` strips 15 and lthebracket 16. The

bracket 16 isfals'o provided with slots andY Quo a tongue which fits the slotslf formed in...Y

the ends of the-strips15. f This prevents the ctrl,

upper edge of the guard from being pushed inward or pulled outward and also prevents the strips 5 from being wedged to the right or to theI left when the strips 5 are locked together.

The strips 5 may be locked by any suitable means, such as by a padlock. ll have, however, shown a simple device which is very difficult to operate, except :trom the inside ot' the window, for eliiciently locking the strips 5 together. The locking means consists ot a cylindrical block 18 which is eccentrically pivoted to one of the strips 5 by means oi a screw 19. A' spring 20 is located intermediate the head'ot` the screw 19 and the bottomof a socket 21 formed eccentrically in the block 18. The block 18 is provided with a pin'22 that enters a hole`23 formed in the strip 5 other than the one to which the block is pivotally secured. rThe eccentric relation of the spring 20 to the block 18 renders it exceedingly difiicult to move the block 18 `so as to raise the pin 22 from the hole 23 when operating from the outside of the window and through the small spaces or cracks formed by the lazy tongs, while from the inside of the window the block 18 may be readily pulled back, pulling in line with the axis of the screw 19 so as to move the pin 22 "from the hole 23. lVhen the block 18 has been pulled from the strips 5 it may be easily'turned so as to unlock the strips.

When the sash 2 Yis lc=wered the position of the bracket 16 is so located on the sash that it will be placed slightly'above the bracket 11 and when the window 2 is raised and the strips 5 are placed in locking position the brackets 11 and 16 engaging with the strips 5 and-15 prevent the sash from being raised any-higher. rthus the space below the sash is securely guarded when the sash is up.

In the forinof the device illustrated in Fig. 5 each of the lazy tongs 4 is connected to the web of a T or l. strip 24 and the strip 24 is secured to a studding 25 located within or at the side of the Jrame 1. rlhe frame 1 is provided with an opening'26 that is formed in line with the sash 2 and of a height sufticient to receive strips 5V and 15 whereby the lazy tong parts may be readily slipped into the casing of the window.

rllhe lazy tongs 4 preferably partake of the form of the lazy tong construction illustrated in Figs. 6, 7 andL 8 wherein the parts ot the lazy tongs when operated. lie close to each other. 1n order-that the window ma be opened at a greater width the parallel `strips of the lazy tongs are pivotally connected at a plurality of intermediate points.

1n the -orm of construction illustratedintong construction together.

invita-77 lock, strips 27 extend from the second lower row of points of connection between the strips to the fourth row of points of connection between the lazy tong strips, which closes the opening between the lazy tong strips that are connected at these points. The upper ends of the strips 27 are slotted while the lower ends have openings about the size of the shanks ot the pins that connect the parts of the lazy The strips 27 are secured by the pins ot the second and fourth rows. rlhe slots permit free movement or action of the lazy tong construction, The locking means 28 is located substantially in line with the third lower rowof points of connection or" the lazy tongs and hence the lock is protected troni any attempt to open the same.

The lazy tongs in the form ot construction illustrated in F ig. 6 are provided with strips 29 and 30 that are liingedly connected together by means of the hinges 31. This divides the lazy tongs into ytour parts 32 and 33. The parts 32 are secured to the bent strips 34 that are hingedly connected to the strips 35. The strips 35 are secured by any suitable vmeans to the Jframe 1 on the window. rThe strips 34 are so bent as to bring the lazy tongs in the plane of the sash notwithstanding the tact that the strips 35 are secured to the inside of the frame as indicated in Fig. 8. The strips 34 arethus bent at an angle so that they will conform to the shape of the frame. y

The lazy tong parts 32 are connected to the strips 30, while the lazy tong parts 33 are connected to the strips 29 and to the strips 36. rllhe strips 30 extend beyond the upper and lower edges of the guard and are provided with slots 37 that engage in brackets 38 and 39 similar in construction to the brackets 11 andV 16. lThe strips 36 are similar to the strips 5 and are secured to brackets 40 and 41 that are also similar to the brackets 11 and 16, whereby the guard is secured in position to the window sash and to the sill ot' the trame when the lazy tong parts are in closed and locked position.

'l/Vhen the lazy tongs are folded together by moving the strips of the' lazy tongs toward each other and the lazy tong parts are folded by means ot the hinges 31 they may be swung to one side of the window by means of the hinges 42.A

1f desired, the window may be locked in Y closed position, that is, with the sash down,

by placing the guard in locked position, and a strip'43 may be placed over a staple 44 and the lockingfmeans 45 securedin the staple. The strip 43 may be pivotally connected to one of the strips 36 and thus may be folded down over the guard when not in use. This provides a convenient means for locking the window whenclosed.

The construction illustrated in Figs. 6 and 7 may also be secured within the window frame as shown in Fig. 5, it being understood that Fig. 5 illustrates an adaptation of the guards illustrated in Figs. l and 6.

I claim l. 1n a Window guard, a pair of lazy tong parts hingedly connected to the frame of the Window and connected to metal strips, a bracket located on the Window sash and a bracket on the Window sill having tongues and slots, the strips having slots, the

tongues of the brackets fitting the Slots of the strips, and the strips fitting the slots of the brackets, means for locking the strips together.
